HAND AUGER SOIL SAMPLING PROTOCOLS
Soil samples will be collected in laboratory-clean glass sample jars, and labeled with the
designation, location, date and sampler. Collected samples will be preserved on ice and
picked up by the analytical laboratory. V3 standard chain-of-custody procedures will be
followed regarding the shipment and receipt of samples.
A hand auger will be used at the Site, to provide for visual observation of subsurface
conditions, and the collection of soil samples at depth. The materials will be returned to
the “hole” in the same manner as removed.
Collected soil samples are visually classified in the field by Site engineer or geologist, in
accordance with ASTM D 2488-84. Sample lithology is recorded using the Unified Soil
Classification System. Soil logs, documenting soil types and subsurface conditions, will
be completed by V3’s Site engineer or geologist.
During sampling activities, soils will be screened for the presence of volatile organic
compounds (VOCs) using a photoionization detector (PID). VOCs are common
components of a variety of environmental contaminants, including industrial solvents,
petroleum products and a wide range of other industrial compounds. The PID is also
used to monitor ambient air concentrations within the work zone during the sampling, in
accordance with V3’s Site Safety Plan. Personal protective equipment is utilized by
sampling personnel during sampling, as specified in the Site Safety Plan.
Soil samples that are collected for laboratory analysis will be placed in appropriate
sample containers in order of decreasing volatility. For each recovered soil sample,
samples for possible VOC analysis will be collected directly from the recovered sample,
in accordance with USEPA SW-846 Method 5035/8260. Laboratory provided preweighed
vials containing the correct amount of preservatives will be used (10 ml of
methanol per vial and a 20% solution of sodium bisulfate (1 gram of sodium bisulfate to
5 ml of water). All samples collected for VOCs will be obtained directly from the
recovered sampler at the specified sample interval using a disposable plastic premeasured
5-gram syringe barrel provided by the laboratory. The barrel will be driven
into the soil surface to remove the soil without exposure to air. The soil will then be
extruded into one 40-ml vial preserved with methanol. The threads of the sample vial
should be cleaned prior to capping. This process will be repeated until two 40-ml vials
preserved with sodium bisulfate are also filled with 5-grams of soil each. One four ounce
jar or smaller will then be filled with soil for dry weight analysis. The samples will be
immediately capped, labeled, and placed on ice. For all additional analysis, the
remaining portion of the recovered sample from the specified sample interval will be
homogenized and placed into appropriate laboratory specified jars. For all additional
analysis, the remaining portion of the recovered sample from the specified sample
interval will be placed into appropriate laboratory specified jars, labeled with the sample
name, sample location, sample depth (if appropriate), date, time, preservative (if
appropriate), and name of sampler. All samples will be immediately placed in a cooler
filled with ice.
To avoid cross-contamination, the hand auger will be cleaned between sampling
locations, and soil residue is removed during this procedure. Sampling equipment used
